Performance Tests
1–54 TDS 500D, TDS 600B & TDS 700D Performance Verification and Specifications
HSet the vertical SCALE to 200 mV.
HPress VERTICAL MENU, then press the main-menu button
Position.
HSet vertical position to –3 divisions (press –3, then ENTER, on the
keypad). The baseline level will move down three divisions. See
Figure 1–17 on page 1–55.
HPress the main-menu button Offset.
HSet vertical offset to +10 volts (+5 volts for the TDS 794D) with the
keypad. The baseline level will move off screen.
HSet the standard output of the DC calibration generator equal to the
offset. The DC test level will appear on screen. See Figure 1–17.
b. Measure the test signal:
HPress SET LEVEL TO 50%.
HPress TRIGGER MENU.
HRead the measurement results from the readout below the label
Level in the main menu, not the trigger readout in the graticule area.
c. Read results (Check against limits): See Figure 1–17.
HCHECK that the Level readout in the main menu is within the
ranges listed in Table 1–6.
